[TOMT] Video of a Group of British Teenage Boys Rapping or Something

All I can remember is that is was a really low quality relatively short video that I'm pretty sure is a popular meme or something in England (I'm Canadian so idk), one of the boys says "[something] cuz we know how to rap" at one point and later on goes "Tell em [name]" and the other guy just says "yeah". I saw like 10 seconds of it in a yt video once and now I can't remember it and it's bugging me
